QUIL'L.

Application 'filed Bee-ember To all whom may concern. U

Be it known that I, JOHN G. BENTLEY, a citizen of the United States, and resident of Glen Rock, in .thecounty of Bergen and State of New Jersey, have invented a new and useiiul improvement inQuills, oi? which the following is a specification.

This application is a continuation in part ofthe subject-nutter contained in my prior application #(illAOO, filed May 25, 1923, on which Patent zit-1,427 9,448 was issued Jan. 1, 1924. he claim in this application reads on Fig. 3 of the patent.

lVhere .a metal filament, such as tinsel, has been wound on a quill o'l ordinary circular form in cross section, it has been necessary to make a quill of very great diameter in comparison to the thickness of wrappings of the filaments around it and it has been also necessary to only put a very thin layer of said wrappings around the quill. Otherwise when the wound quill was in use in the loom, owing to the nature of the metal filament which is smooth, hard and also very heavy, the whole wound mass would have a tendency to slide oil the end of the quill as the shuttle was thrown back and forth in the loom. Therefore, owing to the relatively small amount of filling which can be wound on a quill of this charactor in comparison with what is wound 011 a quill when using other materials, such as cotton, silk, etc. the production of the metal filled cloth was very slow and expensive, this being due to the vast number of quills a weaver would have to put in his shuttles during a day, making it necessary to stop the loom every time a new quill was inserted into the shuttle.

The object of my invention is to produce a. quill in which the metal filament winding will be made to cling to the quill, thus rendering it possible to wind to a far greater thickness than was possiblehereto-fore, without danger of the windings shelling oil the quill and also materially increasing the length of time that a quill will last when weaving in the loom and thus relatively increasing the production.

My invention more particularly includes a quill having one or more spiral grooves extending longitudinally along its winding portion to form a plurality of edges and concave sides, whereby the winding will cling to the quill.

along its winding portion.

Serial No. 679,188.

By my improvement I have found that the thickness of 'thewrappings on the quill can be more than double thediameter oi the empty quill, the edge or edges caused by the irregular shape 01" the quill'along the winding portion thereof serving to grip the metal tightly and distinctly bend :it. The metal. filament between theedges is wound conriparatively loose so that the outer layers haveatendency to sink into :the folds oi the inner ilayers itthese loose points, tlins causing the interlocking of the layers and preventing the windings from shelling oil the quill. This type of winding will not hinder tl'le drawing oil of the filament as it is more or less stiff and has tendency to unwind or spring away from the quill which causes it to form a wide are around the quill so that it will notcatch in any of the edges which would be the case ii the wrappings were of a difierent nature.

The taper or thickness of the quill is not materially important as the wrappings may be wound on and drawn off quills of greatly varying thicknesses and tapers.

The quill may also be made in many different forms in cross section. Several of these forms are illustrated in the accompanying drawings, in which- Fig. 1 represents in side elevation a quill rectangular in cross'section having four spiral grooves extending longitudinally Fig. 2 represents a cross section taken in the plane of the line IIII of Fig. 1.

Fig. 3 represents in side elevation a quill triangular in cross section having three spiral grooves extending longitudinally along its winding portion.

Fig. 4 represents a cross section taken in the plane of the line-IV--IV of Fig. 3.

Fig. 5 represents in side elevation a quill having one spiral groove extending longitudinally along its winding portion.

Fig. 6 represents a cross section taken in the plane of the line VI-VI of Fig. 5.

The winding portion of the quill is denoted by 1, the headed end by 2 and the nonheaded end by 3. The contour of the wrapping is denoted in dotted lines by 4:.

In Figs. 1 and 2, the tour spiral grooves 5 extend longitudinally along the winding portion once around the same, producing the pronounced edges 6.-

In Figs. 3 and 4 the three spiral grooves 7 extend longitudinally along the winding portion partway around the same, produc ing the pronounced edges 8.

In Figs. 5 and 6 the singlespiral groove 9 extends longitudinally along the Winding portion twice around the same, producing the pronounced edges 10.

In all of these forms the edges are provided along the winding portion of the quill for bending the metal filaments, leaving looser portions between the edges so as to permit the interlocking of the several layers of the windings and thus preventing the shelling off of the coils from the end of the quill and destroying the further usefulness thereof.

The provision of these edges also permit the traverse winding of an interlocked mass of the metal filament on the quill, the said mass having a substantial thickness be tween its ends as compared to the diameter of the quill in the. corresponding cross sectional plane.

In all of these forms the grooves areleft hand spirals, the reverse of the usual spiral quill may be sharp or blunt, as the case may be, and that the body of the quill when viewed in cross section may assume many different shapes between such edges or 001' ners so long as the windings will be caused to interlock and permit a substantial thickness of material to be wound and retained on the quill, the same notbeing dependent upon the size of the diameter of the quill, the invention being as applicable to quills of small diameter as to quills of large diameter.

WVha-t I claim is A quill of polygonal form in cross section along its winding portion, the sides being concave.

In testimony that I claim the foregoing as my invention, I have signed my name this "fourth day of December, 1923.

JOHN G. BENTLEY.
